To all wkomvlt may concern I Be it'known that I, SERGIUS VERNET, a

citizen of the United States, residing in New .York city, in the borough of Brooklyn,

' county of Kings, and State of New York,

have invented certain new and useful Improvements in Automobile Bumpers, of

which the following is a specification.

This invention relates to an improvement in automobile bumpers and more particularly to an improvement in end construction of automobile bumpers.

It is one of the objects of the invention to provide a means for securing the ends of a multiple barau'tomobile bumper together which willjbe economical, which can be carried outwithout the use of bolts, nuts or other securing means ordinarily used and which will result in an improved appearance of the ends of the bumper.

Another object of the invention is to rovide a parallel bar automobile bumper w ich can be undetachably assembled as one unit without the'use of bolts, nuts or other usual securing devices, and which can be conveniently polished and plated as a unit thereby providing a streamline continuous finish free from unplated portions which might ermit rusting to start in service;

' Anot er object of the invention is to provide a method and means for securing the ends of a multiple bar bumper together in frictional engagement with the end holdmembers.

Another object of the invention is to provide a means for securely connecting the ends ofa multiple bar automobile bumper together which dispenses with the use of rivets, nuts, bolts and other forms of securing devices which in service become. loosened, permit rattling','etc., to the annoyance of the automobilist.

Various other objects and advantages will appear as the description of the invention proceeds.

Referring now to the drawings which show various possible forms of embodimen of my invention,

In the embo iment of the invention illustrated in Figures 1, 2 and 5 to 9 the bumper comprises a pair of impact members 1 and 2 connected together at the ends 3by means of tubular connecting members 4. Members 4 are preferably of uniform diameter from the top to bottom thereof and are provided the same with a slot 5 in each end of the members 4 bumper bars 1 and 2. The bars 1 and 2 are provided at each endwith curved or hooked shaped portions 6 and 7, curvedpreferably in opposite directions, and havin the outer circumference of the curve of su stantially the same size or perhaps slightly larger than the inner circumference of the tubular member 4. The thickness of the bars 1 and 2 is substantiallythe same or slightly greater than the width of the'slots 5, the circumference of thecurved portions 6 and 7 and the thickness of the bars 1 and 2 being so related to the inner circumference of the tubular members 4 and the size of theslots 5 as to cut into and frictionally fit and be ermanently retained in the tubular memers 4 and slots 5 .when driven into the same. In assembling the bumper, the bar 1' is placed above the to of the tubular member 4 and driven or orced into the upper slot 5 with the curved portion 6 making a firm frictional contact with the inner walls of the member 4 and in a similar way .the lower bar 2 is driven into the tubular member 4 from the other end. The frictional contact of the ends 6 and 7 with the member 4 is suflicient to retain the members in position and to prevent disassembly of the assembled unit and the portions 6 and 7 being curved in reversed directions evercomes any tendency of the tubular member to become warped or to spring out of vertical alinement. The ends of the bars 1 and 2 are fitted together so tightly that no further securing means is necessary to hold the bars and the tubular member together, the slots 5 assisting to some extent by permitting a slight expansion of the ends of the members 4 when the bars are driven therein.

From the standpoint of service and permanency the connection is completed when the parts are driven together in frictional contact. However as a matter of beauty and adornment it is desirable to provide some sort of closure means for the top of the tubular portions 4. I have therefore shown in Figure 6, a pair of heads or knobs 8 at the ends of the tubular member 4, and a rod 9 for holding the knobs in the position. It is to be understood that these knobs are solely for the purpose of ornamentation and play no part in holding the parts of the bumper together. It will be seen that the space 9 intervenes between the inner circumference of the curved portions 6 and 7 and the rod 9 andthat a space 9 intervenes between the caps 8 and the bumper bars 1 and 2 so that there is no frictional or other retaining contact between the knobs 8 or rod 9 and the ends of the bumper bar. It is obvious of course that parts 8 and 9 can be omitted except for the ornamental appearance of the bumper.

The bumper as assembled in Figures 1 and 2 can be polished and plated as a unit, thereby plating all irregular surfaces and being plated after assembly, there is no .chafing or removal of the plate as in bumpers which are assembled and secured together after plating.

Figures 3, 4, 10 and 11 show a more ornamental and fancy shape of bumper bar, constructed according to the principles of my invention. In these figures the ends of the bumper bars 1 and 2 are turned back at the points 6 forming the recurved por tions 10 of the upper and lower bars 1' and 2 The. recurved portions 10 are brought together at the point 11 and secured to the back bar member 12 by means of suitable clips 13. Connecting arms 14 are provided for securing the bumper to the vehicle. In this form of embodiment the tubular end members 4 are provided with a pair of slots 5 in each end thereof "and the curved portion 6 of the bumper bar at its outer bars will make a firm frictional contact with I the tubular members 4*. The slots 5 receive the front bar portions 1 and 2 and the recurved portions 10.

In the embodiment shown in Figure 12, a different form of ornament knob construction is used. This comprises a headed rivet 15 which is loosely fastened in the curved. ends of the bumper bars 1 and 2 by means of a plate 16. the shank of the rivet being spaced from the curved portions 6 and 7 and being of greater length than the width of the bumper bar. -In assembling this embodiment of the bumper. the rivets 15 are inserted in the curved portions and the curved ends are then driven in-the tubular member 4 to make a firm frictional contact therewith. The bumper bars are properly driven to the bottom of the slots 5 so as to draw the rivets 15 as far into the tubular member 4 as possible to hold the rivets from movement or rattling in the bar.

Figures 13 and 14 show a further modified form of the invention in which the bumper bars 1 and 2 are provided with an enlarge ment 17 near each end thereof, having shoulders 18 which are spaced from the end 19 of the bumper bars, a distance equal to or slightly greater than the inner diameter of the tubular member 4", by which the ends of the bars are connected. in assembling this form of bumper, the ends of the bars are driven into the tubular members 4 and the shoulders 18 abut against the tubular members adjacent the 'walls of the slot 5 and the ends 19 of the bars make a firm frictional contact with the opposite side of the tubular members 4", thereby holding the bars and end member. firmly together. In this form of construction'it'is preferred to omit the ornamental knobs or balls. However, if de sired they may be driven into frictional engagement with the ends of the tubular members or may be .retained by flattened bolts extending through the tubular members at Igne or both sides of the ends of the bumper ars.

Figures 15 and 16 show my improvement end construction,using a hexagonal or polygonal shaped-tubular portion 20, the bumper bars 1 and 2 having the curved portions 6 and 7 driven in the slots 5 of the members 20 and being retained therein by friction as in the embodiments above.

As illustrated in Figure 2 the bars 1 and '2 may be made to enter the tubular portion 4 at substantially a tangent line thereby further improving the streamline appearance of the bumper.

It will be understood that various other shapes can be given to the end connecting member-s4 or 20 and various ornamental shapes can be given to the knobs 8 and Three or four bar bumpers can be made on the same principle by using longer end members having deeper slotstherein and the impact bars instead of being parallel may be permitted to cross each other. The invention is not to be limited by thespecific em-' bodiment shown, but contemplates broadly 10* connecting the-ends withthe bumper bars in frictional contact with the connecting member without the use of nuts, bolts or the like and plating the .bar after it has been undetachably assembled as a unit, it being 16 within the scope of the invention to secure the ends of the bumper bars together by means of a solid connecting member fitted on the inside of the curved portions Sand 7 and engaging same with frictional contact.

20 Various modifications and changes may be claims will understood to cover bot round and ipolygonal hollow connecting members unless otherwise limited and the term enlarged is used to cover the enlargement of the end portion by the loops 6 and 77as Well as the thickening of the ends as at I claim 1.
